Confusion prevailed on Wednesday night over Uttar Pradesh Governor Vishnukant Shastri's invitation to Samajwadi Party President Mulayam Singh Yadav to form an alternative government in the state.

While senior Samajwadi Party leader Ambika Chowdhury claimed Yadav has received a communication from Raj Bhawan asking the SP chief to take oath on August 28 at 1500 hours, special secretary to the governor R K Ojha told PTI: "To the best of my knowledge no such communication has been issued so far."
